I just had my surgery 2 weeks ago. Feeling pretty good now. With the help of a good friend we have made some progress on the project 743B. I'm going to try to post some pictures now. The motor should be going in next week if I can get a break in the weather and get the engine bay cleaned out.On my 743 the lines are on the right side when sitting in it you have a 50 50 chance of getting it right and easy to change if not I could look at mine but not sure if they changed from 743 to 743b
